Philip L. Ross,Yulin N. Huang,Jason Marchese,Brian L. Williamson,Kenneth C. Parker,Stephen J. Hattan,Nikita Khainovski,Sasi Pillai,Subhakar Dey,Scott Daniels,Subhasish Purkayastha,Peter Juhasz,Stephen A. Martin,Michael Bartlet-Jones,Feng He,Allan Jacobson,Darryl J. Pappin,Darryl J. Pappin +17 more
TL;DR: It is found that inactivation of Upf1p and Xrn1p causes common as well as unique effects on protein expression, and the use of 4-fold multiplexing to enable relative protein measurements simultaneously with determination of absolute levels of a target protein using synthetic isobaric peptide standards.
Journal ArticleDOI
The characteristics of peptide collision-induced dissociation using a high-performance MALDI-TOF/TOF tandem mass spectrometer.
Katalin F. Medzihradszky,Jennifer M. Campbell,Michael A. Baldwin,Arnold M. Falick,Peter Juhasz,Marvin L. Vestal,Alma L. Burlingame +6 more
TL;DR: A new matrix-assisted laser desorption/ionization (MALDI) time-of-flight/time- of-flight (TOF/TOF) high-resolution tandem mass spectrometer is described for sequencing peptides.
Journal ArticleDOI
Delayed extraction matrix‐assisted laser desorption time‐of‐flight mass spectrometry
TL;DR: In this article, a matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) mass spectrometer system is described, which provides dramatically improved performance over that obtained with identical TOF analyzers operated with constant electrical fields.
Patent
Time-of-flight mass spectrometry analysis of biomolecules
Marvin L. Vestal,Peter Juhasz +1 more
TL;DR: In this paper, a time-of-flight mass spectrometer for measuring the mass-to-charge ratio of a sample molecule is described, which provides independent control of the electric field experienced by the sample before and during ion extraction.
Journal ArticleDOI
The art and practice of systems biology in medicine: mapping patterns of relationships.
J. van der Greef,Stephen A. Martin,Peter Juhasz,Aram Adourian,Thomas N. Plasterer,Elwin Verheij,Robert N. McBurney +6 more
TL;DR: The broad applicability of Systems Biology in pharmaceutical research and development is discussed with examples in disease biomarker research, in pharmacology using system response monitoring, and in cross-compartment system toxicology assessment.
